You seemed to have missed the point of Minor Glyphs. Blizzard themselves said minors were for minor things, like graphical changes.

So far we have gotten three. Two to change what Polymorph does, and one to use the old Tree of Life form.

There is absolutely nothing wrong with having a Glyph for a purely cosmetic use. Some people like the new effects, some people don't. I like the old one better. Does that mean no one should like the new one? No. I think the new effect could look nice, if given a little more work. It looks less like water, and more like sparkling energy in water.

Let's say you play a Paladin. Let's say they change it so every time you cast a healing spell, it had rainbows and unicorns coming from your hands. What would you say to someone who said "deal with it", if you complained about it?

This isn't as bad as that, and in fact isn't a bad effect. But some of us like the older graphics on some things. There is no harm in having a Glyph for that purpose.

And the new Tree of Life form is UGLY. It's based on the male Orc skeleton. So every time you move, you see that slouched-over pose. Not everyone likes the male Orc model.
